BAD BAD SERVICE!!!!!!!!

I took out a Green light policy with Old Mutual August 2017, when I received a copy of my policy , my date of birth on the policy was wrong.I emailed them notifiying them of this and to date I have not received confirmation that this has been corrected. I forwarded a copy of my ID to them as per their request and since then all I get when I email querying if these changes have been made is "your query is being handled ,we will get back to you" .I have requested for proof that my date of birth has been changed in the policy and 9 months later ,I am still waiting. What will happen to my family if I were to die right now ,because I know for a fact that Old Mutual will give them the run around because the date of birth in my policy and my ID do not match. Can someone please sort this out once and for all, I am extremely tired of this back and forth!
